1、Designation:D6164/D6164M21Standard Specification forStyrene Butadiene Styrene(SBS)Modified BituminousSheet Materials Using Polyester Reinforcements1This standard is issued under the fixed designation D6164/D6164M;the number immediately following the designation indicates theyear of original adoption
2、 or,in the case of revision,the year of last revision.A number in parentheses indicates the year of lastreapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This specification covers prefabricated modified bitumi-nous sheet materials reinfo
3、rced with polyester fabric as theprimary reinforcement(see Note 1),with or without granules,which use styrene butadiene styrene(SBS)thermoplasticelastomer as the primary modifier and are intended for use inthe fabrication of multiple ply roofing and waterproofingmembranes.NOTE1Many modified bitumino
4、us sheets are currently marketed withpolyester mat reinforced with glass yarns to improve processing in themanufacture of the finished modified bitumen product and to reducedistortions that may be introduced during production.These glass yarnsare typically a small percentage of the reinforcement and
5、 do not contributeto the physical properties of the finished product so much as to make theseproducts be classified by Specification D6162/D6162M.1.2 This specification is intended as a material specificationonly.Issues regarding the suitability of the specific roofconstructions or application techn
6、iques are beyond this scope.1.3 The specified tests and property limits used to charac-terize the sheet materials are intended to establish minimumproperties.In-place roof system design criteria,such as fireresistance,field strength,impact/puncture resistance,materialcompatibility,uplift resistance,
7、and others,are factors beyondthe scope of this material specification.1.4 The values stated in either SI units or inch-pound unitsare to be regarded separately as standard.The values stated ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combi
8、ningvalues from the two systems may result in nonconformancewith the standard.1.5 This international standard was developed in accor-dance with internationally recognized principles on standard-ization established in the Decision on Principles for theDevelopment of International Standards,Guides and
